To all whom t may concern.'

Be it known that l, Josnrns G. l-lnor, a subject of the King ot Great Britain, and resident of the city of Montreal, in the Province of Quebec and Dominion oit Canada, have invented certain new and useful lmproveniente in Shutter-Einiges, oi' Which the following is a iull, clear, and exact description.

rlhis invention relates to improvements in hinges, and particularly to that type ot separable hinges used for the attachment of summer and Winter shutters to buildings.

rlhe object of the invention is to provide a hinge which may be adjusted to lock the shutter at any angle in open position.

The eiiiciency of present Windovv7 or shutter hinges depends entirely upon the amount that the Window casing projects beyond the Wall. `When this projection is considerable, the open shutter has a certain movement between the wall and the limit set by the hinge, so that rattling is bound to result, and occasionally the hinge may be forced and the shutters slammed. lWhen the Window casing projects very slightly, the Wall limits the opening of the shutter to such an extent that the hinge parts do not properly interlock, and the shutter is liable to be slammed by even a moderately stiff breeze. Another condition of very frequent annoyance is that Windows are frequently placed so close in the Wall angles that one shutter has little more than 90C or 100o of movement, so that it is impossible for the hinge portions to interlock and hold the shutter open, with the result that all kinds of makeshifts are resorted to by the unfortunate possessors of such a Window.

rlhe hinge forming the subject of the pres-x ent invention is particularly designed to overcome all the above enumerated disadvantages, and to this end, one of the meinbers is provided with a fixed recess, and the other member with an adjustable lug, adapted to enter the said recess and hold the shutter at any desired angle.

Fig. 2 is a side elevation of the hinge open.

the center of the hinge pin, showing one method oi' construction.

Fig. 5 is a plan view ci the hinge parts separated.

Referring more particularly to the drawings, 11 designates the socket member and 12 the pin member, each of which consists o'l a flat plate 13 of suitable shape, Which may be, if desired, reinforced by a peripheral bead 14, and which is provided with apertures 15 for the attaching screws. rlhe socket meinber is provided with a horizontally disposed circular projection 16 having a central aperture 17 provided with a suitably disposed radial extension 18. 1n the periphery of the projection 16 a notch 19 of suitable size and depth is formed adjacent the outer edge of he plate 13. 'lhe pin member 12 is provided with a horizontally disposed projection 2O circular in form, but smaller than the proj ection 16 of the socket member 11, and arranged so that when the hinge parts are assembled, it will lie centrally above the projection 16. A pin 21 depends from the projection 20, and is of a size to have free rotary and sliding movement in the aperture 17. rl`he lovver end oi this pin is provided with a radially projecting lug 22 adapted to pass through the radial extension 1S of the aperture 17, and on relative rotation oi' the hinge parts to engage under the projection 16 and hold the parts against separation. A Wa sher 23 having a dotvnbent radial arm 24 is mounted cn the upper surface of the projection 20 by means of a stud 25 and nut 2G. rlhis arm 24 tapers slightly away from the Washer, as clearly shown in Fig. 2, and is sc dimensioned and disposed that on relative revolution oi the hinge parts, it will drop into the recess 19. lt will thus be seen that during rotation of the hinge parts, the pin member 12 is supported on the projection 16 of the socket member 11 by the arm 24, and is held in its proper relation by the pin 21. lVhen the members are relatively revolved, and the arm 24 engages in the notch 19, the hinge part 12 drops until the lovver surface of its projection 2O rests on the upper surface of the projection 16 of the part 11. At the same time, the Wedge shaped arm 24 ts itself tightly into the notch 19, so that relative movement of the parts except in a vertical direction is entirely prevented. For purposes of strength, each of the projections v lowers With the pin' member.

may be supported by ribs 13a extending to the plates 13. l

While the stud 25 may be cast integral with the pin member, and threaded for reception ot' the nut 2G, I prefer to make this member in the manner shown in Fig. 4, that is, the stud 25 is a separate piece made previously to the casting of the hinge part, and inserted in the mold, so that a portion of the stud which is flattened as shown at 27 to prevent rotation is surrounded by the molten metal and tightly gripped by the same, when it contracts in cooling in the manner Well known. I may cast the upper surface of the projection with a central depression 28 having sloping peripheral Walls 29, on which the lower edge ot' the Washer 23 will bear, so that when the nut 26 is tightened down, the Washer will, have an eX- tremely secure irictional grip on the plate 20, so that it Will never slip under the applieation of any force which the other parts of the hinge would withstand.

The operation of the hinge is the same as that of ordinary shutter hinges in opening and closing the shutter, or in changing from summer to Winter shutters. The shutteris merely thrown open, and When the desired degree of opening is attained, the arm 24 drops into the notch, and the Whole shutter To close the shutter, the same is iirst lifted to clear the arm 2liirom the notch 19 andthen swung shut. During the lifting movement, the lug 22 engages the lower surface of the projection 16 and prevents disconnection of the hinge parts. When the hinges are installed, the nut 2S and Washer 23 are loose and the shutter is set in the position, at which it is desired to lock same. The Washer is then swung around until its arm 24C engages in the notch 19, and the nut Q6 is tightened down to hold same securely to the projection 20. It will readily be seen that Whenever the shutter is open to this degree, the arm Will drop into the notch and hold the shutter securely against movem'ent in either an opening or closing direction. If desired, the Washer may be adjusted so that the arm is quite close to the notch 26 during closed shutter position, with the result that the hinge Will lock the shutters in slightly opened position.

I-Iaving thus described my invention, what I claim is l. In a hinge of the character described, a socket member having a notch therein, a pin member revolubly mounted in said socket member, a Washer revoluble on the pin member, an arm on said Washer engageable in the socket member notch, and means for locking the Washer atany desired angle with respect to the pin member.

2. In a hinge of the character described, a socket member having a notch therein, a

Vgin member revolubly mounted in said socket member, a Washer revoluble on the pin member, an arm on said washer tapering toward its free endand engageable Yin the socket member notch,rand means for locking `the Washer at any desired angle With respect to the pin member.V

3. In a hinge of theV character described, a pair of relatively revoluble members, an independent adjustable projection carried by one of said members, and a recessv formed in the other member in the path of said projection.

ll. In a hinge of the character described, a pin member, an arm member mounted on the pin member, a stud supporting said arm member, and a nut on the stud clamping the arm member Vagainst-the pin member.

5. In a hinge of the cha 1acter described, a pin member, an integral pivot pin therein, an arm member adjustably mounted with respect to the pin member, a stud carrying said arm extending longitudinally through the pin, and a nut on said stud adapted to clamp said arm member against the upper end of the pin.

6. In a hinge of the character described, a cast` pin member Vhaving an integral pin, an arm adjustable around the pin, a stud supporting said arm passing lengthwise through the pin, and longitudinally extending projections on said stud Withinthe pin holding the'same against movement in all directions.

In Witness whereof, I have hereunto set my hand, in the presence. of tW'o Witnesses.
